About this trial
Acute respiratory distress syndrome (ARDS) is an inflammatory injury of the lungs caused by various serious illnesses, such as a bacterial or viral lung infection. It is treated by artificial ventilation with the application of positive pressure. Pulmonary injury, coupled with artificial ventilation, can lead to right heart failure which hinders the ejection of blood to the pulmonary circulation. Modern mechanical ventilation modalities have reduced the frequency ("incidence") of this right heart failure in acute respiratory distress syndrome. A large-scale study has shown this a few years ago. However, the evolution of right heart failure during artificial ventilation, and the consequences it has on the patient's cardiovascular status are poorly determined. This study is conducted to improve knowledge in this area. In adult patients hospitalized in intensive care presenting acute respiratory distress syndrome, the investigators will collect the data recorded on cardiac ultrasound, doses of cardiovascular drugs as well as variables reflecting hemodynamic status and cell oxygenation. Data will be collected during the course of ARDS and mechanical ventilation, as well as after weaning from artificial ventilation.

Trial outcomes
Primary outcomes
Incidence and evolution of right heart failure during ARDS
Interpretation of echocardiography during the first 24 hours of treatment, between the 2nd and 3rd day, between the 5th and 7th day and after extubation.
Secondary outcomes
The temporal evolution of the haemodynamic status
Describe the temporal evolution of hemodynamic status, assessed by changes in cardiovascular medication use (type and dose of vasopressors and inotropes, including norepinephrine µg/kg/min or vasopressin U/min) and tissue oxygenation variables from blood samples (including lactate mmol/l and ScvO2, %) on the same days as the echocardiography.
Phenotypic description of patients affected by right heart failure during ARDS
Identification and description of different phenotypes of RV failure in ARDS based on data from ultrasound, haemodynamic and tissue oxygenation characteristics the same day of echocardiography
Association of these different phenotypes with the prognosis
Describe the risk factors for the occurrence of different phenotypes of right heart failure during ARDS
To describe the risk factors for the ocurrence of different phenotypes of right heart failure during ARDS, based on hemodynamic status including systemic and pulmonary arterial pressure (mmHg), medication use (type and dose of vasopressors and inotropes, including norepinephrine µg/kg/min or vasopressin U/min) and tissue oxygenation variables from blood samples (including lactate mmol/l and ScvO2, %), as well as echocardiographic assessment.
